Time ago in the "Poster/Pin-Up Type Entries" page we had this:

Didn't Rom #50 have some handbooky-type stuff in it?
Sort of. It had pages like those from the old Marvel Annuals, i.e. mostly a pin-up with first appearence and basic information about the characters. For the record, the ones covered were: Rom, Hybrid (Jimmy Marks), the Dead (Ray-Na, Serpentyne, Firefall/Archie Stryker, the Prime Director, Terminator, Mr. & Mrs. Clark, Steve Jackson, the Torpedo (Brock Jones), Rom's humanity), Heroes (and an occasional Villain) (Jack of Hearts, the X-Men, Power Man & Iron Fist, the Fantastic Fout, the Sisterhood of Evil Mutants, Sub-Mariner, Shang-Chi, Dr. Strange, the Soviet Super-Soldiers), the Dire Wraiths, and the Spaceknights of Galador/the Spaceknight Squad (Tarm/Seeker, Unam the Unseen, Raak the Breaker, Vera/Scanner, Vola/Trapper, Plor/Pulsar)

Andy wrote this:
Since no one has responded so far to the poster-type entries questions, I'll leave them out entirely for now. However, if some interest emerges later on I'll be happy to go along with where the interest lies.

I suppose we can add the pages from Rom v1 #50, do you agree?
